摘要: 水溶液中聚噻吩电化学变色是其氧化还原反应的颜色效应, 电化学反射光谱可现场研究电化学变色特性。聚噻吩电化学变色的转换时间为10—20 ms, 寿命达10~4次数量级, 保留时间有数分钟。因此, 聚噻吩在水溶液中也可制成较理想的电化学变色显示器。

Abstract: The redox reaction of polythiophene displays electrochromic property, which was measured in situ by the electrochemically modulated reflectance spectroscopy. The electrochromic parameter of polythiophene are as follows, transformation time 10—20 ms
life time 10 circles
time of color maintenance several minutes
polythiophene can be used as an ideal eleetrochromic indicator.
